I think you missed my point. If you can hit a necco wafer the first time every time, you can hit something important the first time every time. Which means you walk away, no matter what you are using, so long as it has enough oomph to get through the skull. I'd rather see someone using a .32 ACP and be able to do that than someone using a .45 ACP and break a clay at the same range half the time.

Shot placement counts a lot more than the size of the lead you are throwing.
